So I hope this is ok but its not a daily game site but this community got me doing suduko some more. From a search I randomly came across https://sudoku.com/killer/hard/ and its fine. Thing is it had this option for killer you could see in the url and I was curious but honestly soduko is challenging enough that I was like. Welllll maybe once im back in the groove with some practice. Anyway I finally clicked on it and I found out it just has an element for using addition and sometimes called sumduko (a name I like a lot better). So far honestly I think easier since you have two ways to find solutions but I like it because I think its nice to practice basic math skills. Like at the store I like to figure price per unit in my head (and because the store likes to mix and match the base units between products). So I feel it eliminates more the the busy work of marking up the puzzle and adds in a bit of basic practice in using simple addition in a fun way. Maybe I will get bored of it but for now its the version of suduko I will be doing.
